This is the IIO driver for devantech srf08 ultrasonic ranger which can be used to measure the distances to an object. The sensor supports I2C with some registers. Supported Features include: - read the distance in ranging mode in centimeters - output of the driver is directly the read value - together with the scale the driver delivers the distance in meters - only the first echo of the nearest object is delivered - set sensitivity as analog value in the range of 0-31 means setting gain register on device - set range registers; userspace enters max. range in millimeters in 43 mm steps Features not supported by this driver: - ranging mode in inches or in microseconds - ANN mode - change I2C address through this driver - light sensor The driver was added in the directory "proximity" of the iio subsystem and the menu in den config is now called "Proximity and distance sensors" Signed-off-by: Andreas Klinger <ak@it-klinger.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
